叁沟矿缓倾斜中厚至厚矿体采矿方法研究

摘要

According to the occurrence conditions of the slowly inclined medium thick and thick orebody in Sangou mine,the combined mining scheme based on sublevel open stope filling method and cemented pillar room and pillar method is proposed,which its process of mining,cutting,stoping and filling are introduced in detail.The results show that the sublevel open stope filling method can adapt to the slowly inclined orebody,which has the characteristics of high recovery rate,low cost and significant economic benefits,and cemented pillar room and pillar method is suitable to the smaller orebody.The expectant effect of the combined mining scheme is obtained,which can provide the basis for the reasona-ble and economical mining.%针对叁沟矿缓倾斜中厚至厚矿体的赋存条件，提出了分段空场嗣后充填法和胶结矿柱房柱法联合开采，介绍了联合采矿方法的采准、切割、回采、充填过程。结果表明：分段空场嗣后充填法能够较好地适应缓倾斜厚矿体，回采率高，成本低，经济效益显著，同时，房柱法又能很好地解决小矿体的开采问题，联合采矿方法取得了预期的效果，为矿山合理经济开采提供了依据。
